I’m a new Advanced Installer for Marlin in Orlando. I can perform PKC21, VCU24, PDU400, and Partial ADAS 3.1.1 (Hydra & FCM) Updates.

We’d need to set aside 2-3 hours per vehicle. In the most ideal situations we can do it in 1.5, however the Hydra module takes the longest to flash, and if there are any issues we’d need to start again from the top.

A waiver is required before proceeding, and you must be a current/active FOA Member.

Feel free to leave a comment here or send a DM, if you do send a DM please still comment as it may get sent to my other messages folder.

I also work in aviation, so at some point I will be able to travel to areas that may not have an installer readily available to assist.

DISCLAIMER: The following guide is informational and educational. Proceed at your own risk. Any damage or firmware corruption is your responsibility. If you are not comfortable with these steps, do not continue. No support is provided.

Note: Subreddit Moderator u/Latinriky78 has already provided a simpler method to upgrade to build 7475. If you prefer to use that method and wait for the 8963 OTA, please view their guide here: Link to /u/Latinriky78's post.

Prerequisites

Windows Computer

USB-A to USB-A Cable: This is uncommon but can be found on Amazon. Alternatively, connecting a USB-C to USB-A cable in reverse (plugging the USB-C end into your computer) may work, though varying cable standards mean this is not guaranteed.

Pin-hole Tool: A toothpick, SIM eject tool, or safety pin.

Data Loss Warning: This method will perform a Factory Reset on your device. You will need to log in again, redownload apps, and set your preferences from scratch.

Required Files

Dune HD Factory Image (14.8.8963): Download ZIP (Source directory: dune-club.info). You will need to extract the .img file from this archive.

Amlogic USB Burning Tool (Dune Specific AV3.1.18): Download ZIP

Note on Cross-Flashing: You are effectively cross-flashing your Homatics branded device. This will give you the full version of 8963, but it will not activate the Dune-specific features, as those are linked to a Dune Sold specific device UUID.

Instructions

Install the USB Drivers: Unzip the Amlogic USB Burning Tool. Open the folder, scroll down to the driver subfolder, and run dpinst64. Alternatively, right-click the .inf file and select 'Install' from the sub-menu.

Load the Firmware Image: Go back to the main folder and run Aml_Burn_Tool. In the top left, click Setting, then click Load Img. Navigate to your extracted 14.8.8963 folder and select the aml_sei804hm_dune.img file. Give it a moment to load.

Start the Burning Tool: Use the default settings. Do not click the key overwrite option. Click Start. The program will enter a Listening mode.

Connect the Device: Ensure your Homatics Box R is powered off and unplugged. Plug the USB-A cable into the blue port nearest the power jack, and the other end into the computer.

Enter USB Burning Mode: Locate the reset button directly under the USB-A port. Insert your pin-hole tool, press, and hold the button. While holding the button down, plug the power cable into the device.

Flash the Firmware: The device will initially display "Fastboot". Keep holding the reset button until the display reads "USB BURNING". Once this appears, remove the pin-hole tool. The software on your computer will take over.

Complete the Process: Wait for the green progress bar to complete. The bottom of the software window will state "Burn Successful".

Reboot and Setup: Power off the Homatics box and unplug the USB cable. Plug the device in normally to power it on. It will boot to the remote pairing screen. You will need to hold the Home and Back buttons slightly longer than usual to successfully re-pair the remote. Proceed with standard device setup on the latest version.

This film could have served as the perfect stealth opening for an SCP Cinematic

Async appears to operates like the SCP Foundation. They use containment protocols, exploration tactics, and have that same cold corporate attitude. When the Async team neutralizes Mary with gas at the end, it felt like agents administering amnestics to cover up a civilian breach.

If they had replaced Async with the Foundation, or just flashed an SCP logo on a uniform in the final frames, it would have been a massive reveal similar to the ending of Split.

Since the ending is open, they could still retcon Async into the SCP universe. A sequel could reveal Async as a corporate front or a civilian company that got in over its head, forcing the actual Foundation to step in and take over containment.

Optoma released a new firmware update for the CinemaX series on March 19, 2026. This update does not present itself as an Over-The-Air (OTA) network update (At least not on my CinemaX Pro), so you will need to flash it manually via USB.

The U.S. support site no longer lists downloads. I found them on the European Optoma site. Then I couldn't find the P1 due to the regional naming convention of the P1 being sold under a different model number abroad, UHZ65UST.

The CinemaX P1 and CinemaX Pro use the same firmware as the European UHZ65UST. Flashing the UHZ65UST firmware onto a US CinemaX Pro works perfectly.

Here are the download links for each model:

Key Changes in This Release

The documentation lists the system firmware as version 17.2, but once installed, the projector info screen correctly identifies it as C18.

• HDMI 2.1 / 8K AVR Handshake Fixes: Resolves sync loops, snowy images, black screens, and incorrect resolution detection when connected to modern Denon, Yamaha, and Marantz receivers.
• Expanded Audio Delay: Internal speaker delay limits have been increased to +/-150ms (Auto Settings) to better address lip-sync and audio alignment issues. This applies only to the built-in soundbar.
• Discrete Power Off Command: Added support for a discrete IR/BT "Power Off" code. The full hex code list can be found on the product download page.
• UI Bug Fixes: Corrected an issue from previous builds where audio settings values would incorrectly display as zero or negative.
• App Removal: The unsupported iQIYI application has been removed from the marketplace.

If you have been dealing with handshake drops or audio sync issues on your setup, this update is worth the manual effort. Make sure to use a FAT32-formatted USB drive for the flash process.

EDIT: u/Smagdali over on AVSForums pointed out that these FWs somewhat address a serious security vulnerability in these projectors that he discovered: https://whitelabel.org/security/2026-02-01-smart-projector/

I thought this was more common knowledge since the update occurred last year, so I wanted to help spread awareness since it looks like it’s not well known. I used to ship with PirateShip but have moved to eBay labels because of this change.

https://www.ebay.com/sellercenter/news/2025-september/inr-policy-updates

https://www.ebay.com/help/policies/selling-policies/seller-protections?id=4345 (Scroll down to ‘Other protections’ then click on ‘eBay Money Back Guarantee requests’ under ‘If a buyer reports that an item hasn't arrived’ it states ‘Additionally, we’ll protect you if you use an eBay label and the item is delivered to the buyer after you’ve issued a refund. We'll automatically reimburse you for the item, remove defects, and exclude the case from service metrics.’

I get both sides of the argument, it’s not that most of us can’t afford an extra $5 ($120/yr vs $60/yr), it’s a ‘luxury’ after all, it’s the principle of the value, at $5/mo who cares, it’s a nice to have backup, at $10/mo it’s now crossed the threshold of a service that I actively use daily, which this wouldn’t fall into for most people. I can see though where this is perfect for an always on offsite IOT only network.

On the flip side, you’re talking about a satellite service that even 6+ years ago wasn’t even an option, with shitty HughesNet costing $150+ for garbage service, Starlink has made high speed satellite internet highly available to more people. On the surface, even $10/mo isn’t bad for what it is, but, since they launched the Standby plan at $5/mo initially, it has ‘anchored’ the price for people, and now any increase will be seen as a shitty value.

I have AT&T Fiber, I strictly had this for a backup in a hurricane prone area, for me, $10/mo isn’t worth it for the backup option that may get used once a year, $5/mo was.

EDIT: At $10/mo for Unl Low Speed is where I’d now rather spend the $5 extra for Unl High Speed 5G, Computers4People resells T-Mobile High Speed sims for $14.99/mo which I have at my moms place as her primary ISP. They do shape traffic shape/throttle streaming services to 1.5Mb/s but that can be bypassed with a VPN. Outside of that she gets ~400/60 service on a UniFi 5G Max connected to a UDR7.
